Application Scope of JINCHAN ① Applicable ore types: golden and silver oxidized ore, primary ore, high-sulfur and high-arsenic gold ore, cyanidation slag, gold concentrate, pyrite cinder and anode mud etc; ② Applicable beneficiation process: dump leaching, pool leaching and carbon pulp (agitation leach) etc. 2. JINCHAN Product Form: Granular or powder form 3. JINCHAN Dissolution Method: it can be used after being fully dissolved by water under normal temperature (in general, the dissolution can be accelerated in flowing water or through full stirring; dosing pool can be built near to the barren solution pool in heap leaching process in order to let backwater which has passed carbon directly wash JINCHAN and dissolve it into barren solution pool); 4. Alkalinity Adjustment: in general, adjustment is carried out with lime or caustic soda with stable pH value between 11-12; when the pH value of backwater decreases, alkalinity shall be timely adjusted; when the pH value is too high (more than 12) for a
